Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the argon is helium
Helium, another rare gas, has its own specific subheading 2804.30, separate from argon.
If for other specified gas mixtures containing argon
Processed gas mixtures with argon for industrial use beyond pure form go to heading 3811.
If imported as part of a machinery refrigerant system
Argon used in assembled machinery or equipment is classified by function under 8419, not as a standalone chemical.

Import Tips & Compliance
• Include material safety data sheets (MSDS) and purity analysis reports; label cylinders per 49 CFR hazardous materials regulations
• Avoid declaring cylinder deposit values separately to prevent duty overcharges
